public class MRZCodeDetectionCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

'Declaration

Public Class MRZCodeDetectionCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage

Dim instance As MRZCodeDetectionCommand

public sealed class MRZCodeDetectionCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.Core.MRZCodeDetectionCommand()

public ref class MRZCodeDetectionCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

This command searches inside a given LeadRect zone (set using SearchingZone property) and detects an MRZ code.
Users can get the detected zone by calling the MRZZone property.
